Less Adverts - More Trailers

Since when did the trailer spot at the cinema become just another time to advertise your product?

During my recent 3 cinema weekend I noticed a (new?) trend for slipping adverts into this, in my eyes, ‘sacred’ time.  First we got an advert for advertising at the cinema which was pretty badly received indicating just what a poorly judged advert it is.  We were then treated to an all-in-one trailer for Autumn Cinema, a collection of blink-and-you’ll-miss-it clips from a number of different productions due for imminent release.  While I can see what this advert is trying to achieve I’m just not thrilled to see it take the place of a full length individual trailer.  Finally we have the Orange advert, ‘cunningly’ disguised as a trailer for Gulliver’s Travels.  These Orange ads used to be a lovely little separate entity but now they are just another threat to my beloved trailers.  
My main complaint is that the adverts have just finished.  I sat through them all.  I did my bit.  Why, when we finally get to the good stuff do you hit me with more adverts?  I’m especially annoyed by adverts in cinema advertising the cinema.  I’m here!  You’re preaching to the converted!

Please bring back my trailers.
